Unified description of hadron-photon and hadron-meson scattering in the Dyson-Schwinger approach [PDF]

open access: yes, 2011
We derive the expression for the nonperturbative coupling of a hadron to two external currents from its underlying structure in QCD. Microscopically, the action of each current is resolved to a coupling with dressed quarks.

X-ray scattering from a plane parallel slab using radiation transfer considerations [PDF]

open access: yesarXiv, 2020
X-ray scattering power of a plane parallel homogeneous slab of material is derived using radiation intensity transfer equations.The scattering power scales with the ratio of the scattering coefficient of interest to the total attenuation coefficient. The results can be used to guide the choice of slab thickness, scattering geometry and photon energy to

Prospects for measuring coherent neutrino-nucleus elastic scattering at a stopped-pion neutrino source [PDF]

open access: yesPhys.Rev.D73:033005,2006, 2005
Rates of coherent neutrino-nucleus elastic scattering at a high-intensity stopped-pion neutrino source in various detector materials (relevant for novel low-threshold detectors) are calculated. Sensitivity of a coherent neutrino-nucleus elastic scattering experiment to new physics is also explored.

Measurements of top-quark pair differential cross-sections in the lepton+jets channel in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV using the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
Measurements of differential cross-sections of top-quark pair production in fiducial phase-spaces are presented as a function of top-quark and tt¯ $$ t\overline{t} $$ system kinematic observables in proton-proton collisions at a centre-of-mass energy of ...

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Modulated 3D cross-correlation light scattering: improving turbid sample characterization [PDF]

open access: yesRev. Sci. Instrum. 81, 123107 (2010), 2010
Accurate characterization using static light scattering (SLS) and dynamic light scattering (DLS) methods mandates the measurement and analysis of singly-scattered light. In turbid samples, the suppression of multiple scattering is therefore required to obtain meaningful results.

Search for W W/W Z resonance production in ℓνqq final states in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
A search is conducted for new resonances decaying into a W W or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically.

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Search for supersymmetry in final states with missing transverse momentum and multiple b-jets in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks into the lightest neutralino χ˜10 $$ \left({\tilde{\chi}}_1^0\right) $$ is reported.
